What is wrong with my MacBook Pro and iPhone?

My MacBook and iPhone 5s have been acting strange today. So this morning my MacBook informed me that iTunes had an update. I didn't feel like updating it so I clicked the x to close the box. ITunes then repeatedly starting opening itself up and playing 2 of the songs from my library. Each time I force quit, iTunes would open itself up and play the same two songs again. The more I forced quit the faster iTunes would open itself and play the 2 songs. I then restart my laptop. Later I was listening g to music on pandora when no matter what song, it keep pausing and playing over and over again. I then switch to my phones music library but that music also keep pausing and playing itself. I was then face timing but FaceTime hung up itself twice. Siri also kept activating itself but I never pressed the home button. Any ideas as to what the issue might be?

Take to apple

  • Will Google+ Photos distinguish photos from my iPhone and my Macbook Pro? I have Google+ backup for both my iPhone and my Macbook Pro (iPhoto) and I was wondering if it would distinguish pictures from the two. Like… "Photos from your iPhone" & "Photos from your Mac" Or, does it just upload them all into one place, and categorize all the photos just by date?
  • MacBook Pro and iPhone I recently purchased a macbook pro and I'm having trouble with my photos. My iCloud says I have 1,297 photos which is taking up 3.78 GB but on my phone it says I only have 454 photos (which is correct). Why does it say there are so many more? And how do I transfer the 454 photos on my macbook?
  • Is getting a ipad air worth it if you have the iphone 5 and MacBook Pro? I'm thinking of buying myself a ipad air for christmas but I already have the iphone 5 and MacBook Pro. Should I spend the money on something else or is the ipad a waste of money if I have those 2 gadgets? What's the point of the ipad?
  • IPhone 5S and Macbook pro, or Android phone and windows laptop for college? So i have an iPhone 4S, and i want to try something different because i've had many problems with it. I've come to the conclusion that for college i should get apple or android for college. If i went for apple, it would be an iphone 5S, and a macbook pro. I don't have a clue about android or windows laptops, so if you could recommend phones and laptops.
